Exodus 28:4

28:4 Now these are the garments that they are to make: a breastpiece, ¹  an ephod, ²  a robe, a fitted ³  tunic, a turban, and a sash. They are to make holy garments for your brother Aaron and for his sons, that they may minister as my priests.

Exodus 28:30

28:30 “You are to put the Urim and the Thummim ⁴  into the breastpiece of decision; and they are to be over Aaron’s heart when he goes in before the Lord. Aaron is to bear the decisions ⁵  of the Israelites over his heart before the Lord continually.

[28:4]  ¹ sn The breastpiece seems to have been a pouch of sorts or to have had a pocket, since it was folded in some way (28:16; 39:9) and contained the Urim and Thummim (Exod 28:30; Lev 8:8).

[28:4]  ² sn The word “ephod” is taken over directly from Hebrew, because no one knows how to translate it, nor is there agreement about its design. It refers here to a garment worn by the priests, but the word can also refer to some kind of image for a god (Judg 8:27).

[28:4]  ³ tn The word תָּשְׁבֵּץ (tashbets), which describes the tunic and which appears only in this verse, is related to a verb (also rare) of the same root in 28:39 that describes making the tunic. Their meaning is uncertain (see the extended discussion in C. Houtman, Exodus, 3:473-75). A related noun describes gold fasteners and the “settings,” or “mountings,” for precious stones (28:11, 13, 14, 20, 25; 36:18; 39:6, 13, 16, 18; cf. Ps 45:14). The word “fitted” in 28:4 reflects the possibility that “the tunic is to be shaped by sewing, … so that it will fit tightly around the body” (C. Houtman, Exodus, 3:475).

[28:30]  ⁴ sn The Urim and the Thummim were two objects intended for determining the divine will. There is no clear evidence of their size or shape or the material of which they were made, but they seem to have been familiar items to Moses and the people. The best example of their use comes from 1 Sam 14:36-42. Some have suggested from the etymologies that they were light and dark objects respectively, perhaps stones or sticks or some other object. They seem to have fallen out of use after the Davidic period when the prophetic oracles became popular. It may be that the title “breastpiece of judgment” indicates that these objects were used for making “decisions” (J. P. Hyatt, Exodus [NCBC], 283-84). U. Cassuto has the most thorough treatment of the subject (Exodus, 378-82); he lists several very clear rules for their uses gathered from their instances in the Bible, including that they were a form of sacred lot, that priests or leaders of the people only could use them, and that they were used for discovering the divine will in areas that were beyond human knowledge.

[28:30]  ⁵ tn Or “judgment” (KJV, ASV, NASB, NRSV). The term is מִשְׁפָּט (mishpat), the same word that describes the breastpiece that held the two objects. Here it is translated “decisions” since the Urim and Thummim contained in the breastpiece represented the means by which the Lord made decisions for the Israelites. The high priest bore the responsibility of discerning the divine will on matters of national importance.
